650/1310nm Fused WDM Coupler 650/1550nm Wavelength Splitter

Lfiber’s 650/1310nm or 650/1550nm fused WDM coupler (wavelength selective coupler, wavelength combiner/splitter) is based on fused fiber and fused biconical taper (FBT) technology. It obtains light from two inputs with different wavelengths (650/1310nm or 650/1550nm ) and feeds it into the same output fiber. When used in the reverse direction, the WDM coupler is capable of separating the two wavelengths. It features low Insertion loss, low PDL, high reliability and stability. Related Products ↓

650/1550nm and 650/1310nm Fused WDM Coupler (Wavelength Combiner/Splitter, Wavelength Selective Coupler, Dichroic Coupler)

The transmission characteristics of 650/1310nm or 650/1550nm fused WDM couplers are wavelength dependent, so it’s also called wavelength combiner/splitter, wavelength selective coupler, or dichroic coupler. With excellent FBT method, Lfiber designs and manufactures classical and specialty fused WDM couplers according to the customer request. A broad range of designs (fiber types, operating wavelengths, handling power, connector types, package sizes, etc) are available, please contact us to get more information. Lfiber’s fused WDM couplers are good choices and extensively used for telecommunications applications, CATV networks, fiber amplifiers, R&D, and many other industries.
